REMEMBER: BogoMIPS, are bogus only - they DO NOT tell you anything about
your processors real performance. So, I guess, the calibration loop used for
calculation BogoMIPS is somehow broken if you compile 2.0.36 for 686 instead
of 586 (as advised in Help to "Processor type").

You probably haven't lost any performance (apart from possible speedups 2.2.0 
might bring along).

Bye, Tino.
